Meningioma: Treatment, Surgery & Recovery in Malaysia

Meningioma is the most common primary brain tumour in adults — accounting for over 36% of all primary brain tumours. Most are benign. Most grow slowly. And when found early and managed well, most are curable.

This is a condition where the surgeon’s decision-making matters as much as the surgery itself — because not every meningioma needs to be operated on immediately, and operating on the wrong one at the wrong time can cause more harm than good.

What Is a Meningioma?

A meningioma is a tumour that arises from the meninges — the three-layered protective membrane surrounding the brain and spinal cord. The majority (80–85%) are Grade I: benign, slow-growing, and unlikely to spread.

They are more common in women (2:1 ratio), and most commonly diagnosed in adults aged 40–70. They can occur anywhere along the brain surface or skull base — and location determines both symptoms and surgical complexity far more than grade alone.

Meningioma Grades

Locations and What They Mean

Convexity meningioma — on the surface of the brain. Most surgically accessible. Excellent outcomes with complete resection.

Sphenoid wing meningioma — at the base of the skull near the eye socket. Can involve the cavernous sinus or optic nerve. Requires meticulous dissection to preserve vision.

Parasagittal / Falx meningioma — along the midline, adjacent to the superior sagittal sinus. Venous anatomy must be respected. Complete resection possible in most cases.

Skull base meningioma — petroclival, foramen magnum, olfactory groove. Among the most technically demanding surgeries in neurosurgery. Cranial nerve preservation is the priority alongside tumour removal.

Spinal meningioma — within the spinal canal, compressing the spinal cord. Causes progressive weakness and sensory loss. Highly curable with surgery.

Symptoms of Meningioma

Because meningiomas grow slowly, symptoms often develop gradually and may be dismissed for months or years. Symptoms depend on location:

• Headache — typically positional, worse in the morning
• Seizures — new-onset epilepsy in an adult should always prompt MRI
• Visual changes — loss of peripheral vision, double vision
• Hearing loss or tinnitus — for posterior fossa or petrous tumours
• Weakness or numbness in arm or leg
• Changes in smell — anosmia for olfactory groove meningiomas
• Cognitive change — memory, concentration, personality

Many meningiomas are discovered incidentally — found on a scan performed for another reason (headache work-up, trauma, routine health screen). Managing an incidental meningioma requires careful judgement about when to watch and when to operate.

Does Every Meningioma Need Surgery?

No. This is one of the most important conversations I have with meningioma patients.

Surgery is recommended when:

• The tumour is causing neurological symptoms
• There is evidence of growth on serial imaging
• The tumour is large and at risk of causing symptoms
• The patient is young with a long expected follow-up period
• Grade II or III on imaging characteristics

Observation (watchful waiting) is appropriate when:

• The tumour is small (< 3 cm), asymptomatic, and incidentally found
• The patient is elderly with significant comorbidities
• The tumour is in a high-risk location where surgery risk exceeds tumour risk

If you’ve been told you have an incidental meningioma and are not sure whether to operate, this is precisely the kind of second-opinion question I field regularly.

Surgery: What I Do

Complete surgical resection — removing the tumour and its dural attachment point — gives the best long-term outcome and lowest recurrence rate.

The Simpson Grade system classifies completeness of meningioma resection: Grade I (complete resection including dural sinus) carries a <10% recurrence rate at 10 years. Grade IV–V carry higher recurrence and typically require adjuvant radiotherapy.

For skull base meningiomas, the goal shifts: nerve and vascular preservation becomes as important as extent of resection. Attempting to remove every last tumour cell at the expense of vision, hearing, or facial movement is not the right trade-off. I will discuss this explicitly with you before any skull base surgery.

Techniques I use:

• Frameless stereotactic navigation for all craniotomies
• Intraoperative neuromonitoring (MEP, SSEP, cranial nerve EMG)
• Awake craniotomy for tumours near speech or motor areas
• Surgical microscope with fluorescence (5-ALA) for atypical or recurrent cases

Recovery After Meningioma Surgery

Hospital stay: 3–5 days for most convexity and parasagittal meningiomas. Longer for skull base cases.

Return to driving: Not until seizure risk is formally assessed — typically 3–6 months if seizure-free.

Return to work: Light duties in 4–6 weeks for desk work. Heavy physical work: 8–12 weeks.

Follow-up MRI: At 3 months post-op, then 1 year, then every 2–3 years for Grade I. More frequent for Grade II/III.

Frequently Asked Questions

Q: I have a 2 cm incidental meningioma. My GP wants to operate immediately. Is that right? Not necessarily. A small, asymptomatic meningioma in an otherwise healthy adult can often be safely observed with 6-monthly MRI for the first year, then annually if stable. The decision depends on your age, health, tumour location, and growth rate. I would want to review your scans before recommending surgery.

Q: Will removing the meningioma cure me? For Grade I meningiomas with complete resection (Simpson Grade I/II), long-term cure rates exceed 90%. Grade II meningiomas have higher recurrence — adjuvant radiotherapy reduces this. Regular MRI follow-up is always necessary.

Q: I’ve been told my meningioma is near a major blood vessel. Is that dangerous? Proximity to the cavernous sinus, superior sagittal sinus, or major cerebral vessels significantly increases surgical complexity. This is where surgical experience, not just technique, matters. I will show you the vascular anatomy on your MRI and explain exactly what the risks are.
